Parkour is not a sport, in that there are no rules, teams, or points. It is not about competition or showing off.
It shouldn't be confused with freerunning. Freerunning is more about free-movement and involves more tricking.
Parkour can be thought of as being chased by someone. You want to get away as fast as possible, right? But lets say you begin running into rails or walls or other obstacles as such. If you go around them you're only wasting time and energy.
The trick of parkour is to use as little wasted movementt while going past an obstacle. This is why most consider tricking and flips "not parkour" as they simply aren't necessary and will most likely slow you down in someway.
To parkour is to be able to control your body and mind into one being, so that you can find a path quickly, and move your body in a way that the path can be followed into the next path you're given. If you're running towards and obstacle and start to slow down in order to maneuver around it, most likely you need to practice more.
"The bus didn't come, and I only had 10 minutes to get to work. I realized it was the perfect opportunity to put my parkour-training to work."
Parkour is a way of moving from one place to another as quickly and as efficiently as possible by means of jumping, vaulting, climbing and other such things.
Parkour is not to be confused with freerunning, which is more focused on aesthetics (i.e. flips, aerials etc.) rather than efficiency. Freerunning is considered an extreme sport, wheres Parkour is a practice for personal benefit rather than showing off.
One who practices Parkour is known as a traceur
It includes such techniques as the tic-tac (wall step/run); kong (a form of vault); and precision (two-foot to two-foot jump) among myriad others. Most watching traceurs pk would describe their movements as series of of actobatic techniques fluidly integrated into a continuous run from A to B, past, over under and through any obstacles in their path. However, that would be during a run (most of which are filmed, as with skaters). Most often, if you saw traceurs practicing they'd be honing individual components of their technique.
Certain individuals have chosen to explore alternative forms of parkour, such as running through traffic or passing through crowds quicky, while others, such as Team Ryouko or Xyndicate have attempted to blend pk's unique ideals with other forms of martial and athletic arts.
